Hair testing is increasingly perceived as a robust method for uncovering drug and alcohol consumption. Hair captures a comprehensive historical record of substance use by encapsulating biomarkers within the hair strand as it grows. When harvested near the scalp, hair can indicate substance use over a detection period of roughly three months. The collection of hair is straightforward, relatively tamper-resistant, and convenient to transport.
A 1.5-inch cut from approximately 200 hair strands (around the girth of a #2 pencil) nearest the scalp yields 100mg, the optimal amount for analysis and validation. For assessments like EtG, additions, and/or evaluations beyond 10 panels, 150mg of the hair sample is advised. It's suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unobtainable, an equivalent volume of body hair could be gathered. In the context of head hair, it specifically pertains to scalp hair. Body hair encompasses any other hair varieties (e.g., facial, axillary).
Process Overview
The laboratory handling of a drug test outcome incorporates four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial incorporation of a specimen into the laboratory’s operation. This stage involves ensuring that the sample was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and carrying out any supplementary data input that an electronic chain of custody system did not furnish.
Screening encompasses a preliminary rapid assessment for illicit substances. While cost-effective for excluding drug use in most samples, a positive screening outcome requires corroboration for legal acceptability. Any samples deemed presumptively positive during Screening necessitate a confirmative reevaluation.
Presumptively positive samples during the Screening phase prompt further extraction from the original specimen for the Extraction stage. Here, drugs are removed from the hair at a significantly diluted concentration compared to other techniques (e.g., urine or oral fluid), rendering hair drug screening a notably challenging practice.
Confirmation for any positive Screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, all presumptive positive specimens are washed as appropriate. The comprehensive laboratory procedure, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
